STOP FOR WINIDOW-BLINDS.

SPECIFICATION forming part of Letters Patent No. 703,626, dated July 1, 1902.

Application filed May 9, 1901.

120 all whom it may concern.-

Beit known thatI, THERON A.UPSON, a citizen of the United States, residing in .the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Stops for Win-, (low-Blinds, of which the following is a specification.

In my application for patent, No. 50,587, dated March 11, 1901, I provided an improved stop for window-blinds, which is arranged to be attached to one member of a blind-hinge and to bear against the inner side of the other member, thus holding the blind in the open position.

My present invention aims to provide an improvement upon such a stop which is simple and cheap in construction and which is easily manipulated or attached to blindhinges and which comprises various improvements in detail, hereinafter set forth.

Referring to the accompanying drawings, showing specific embodiments of my present invention, Figure lis a perspective view of my improved stop in position and holding a blind open. Fig. 2 is a longitudinal section of the same, the position for permitting the blind to close being shown in dotted lines. Fig. 3 is a horizontal section. Figs. 4 and 5 are similar horizontal sections of modifications. Fig. 6 is a detail.

One of the important features of improvement inmy present stop is the arrangement of the stop so that it is easily movedout of the path of the blind to permit the blind to swing in. For this purpose it is preferably pivoted so as to permit of being swung downward without the necessity of releasing any fastening device, as in the embodiment shown in my previous application. For example,referring to the drawings, the stop A, comprising, preferably, a screw-shaft A and heads A and A is carried on a swinging arm B, pivoted at its lower end, so that the stop may be swung about such pivot-point and downward out of the way of the blind member 0 of the hinge, as shown in dotted lines in Fig. 2. The stop A is laterally adjustable by screwing it through the upper end of the swinging arm B, substantially as in my previous application. The swinging arm B is attached, as explained, to any suitable means Serial No. 59,487. (No model.)

for connecting it to the fixed member D of the hinge. As the pressure by the hinge member 0 on the head A of the stop is sometimes outward, as well as directly lateral, it is advisable to provide some means for preventing the stop from being pushed outward and then falling out of the path of the mem' her 0. For this purpose I preferably provide on the hinge member D, either separable therefrom or a permanent part thereof, a pin E, upon which the swinging arm B is pivoted, and some additional means for locking the arm against outward movement when in its stopping position. Various locks may be provided against this movement, but I preferably employ a pin F, which is arranged to rest in a slot B in theswinging arm B when the latter is in its upright position. In order to bring the slot B into engagement with the pin F, the bearing of the arm B on the pin E is also in the form of a slot B so that after the arm has been turned into the vertical position it can be lifted, and the slot B, which is L-shaped, as shown in Fig. 2, can be brought into engagement with the pin F, after which the arm is lowered and is thus firmly held against outward movement. For dropping the arm 'it is only necessary to lift it slightly and then swing it outward.

When my improved stop is to be attached to an old hinge, the pivot-pin E and lockingpin F maybe carried in a sleeve G of any suitable design, preferably composed of a pair of identical members Gr, Fig. 3, which are arranged to surround the hub D of the fixed member of the hinge and which have at their outer sides flat extensions G which carry the pins E and F and between which the arm B works. The pins E and F preferably consist of rivets, as shown, which act to hold the parts G of the sleeve together and upon the central portion of which are carried sleeves H, Fig. 3, which act to space the parts G properly apart. I thus provide a very cheap and very firm construction for carrying and locking the arm B, for guiding it in its movement, and for holding it rigidly in the operative position.

Any suitable means may be provided for attaching the sleeve G to the hub D. Preferably a set-screw J is employed for this pur- ,pose, whose head may be provided with a groove J for a screw-driver. When the hub D is of such a size as to nearly fill the sleeve G, the edge G of the sleeve will bear against the body portion of the member D of the hinge, so as to resist a turning movement of the sleeve about the hub by reason of the great pressure on the blind. WVhere, however, the hub D is considerably smaller than the sleeve G, I prefer to interpose a fillet K between the end of the set-screw and the hub D. The edge K of the fillet, Figs. 3 and 6, will then bear against the body portion of the fixed member D of the hinge to prevent movement of the sleeve about the hub. The outer face K of the fillet is flattened, as is the end of the set-screw, so that these two parts bear firmly against each other to prevent any relative movement of each other to permit turning of the sleeve about the hub.

Where it is desired to make my improved stop a permanent part of the hinge, the members G of the sleeve may be cutaway, as shown at G, Fig. 4, and attached by screws L or otherwise to the hub D. The extensions G carrying the pins and the swinging member, may be the same as in the previously-described construction, or the same results may be obtained more simply by extending the portion D not only around the pin M to form the hub D, but beyond the same to form integral therewith the extensions G between which the pins E F and the swinging member I) may be carried. When the pin M is quite small as compared to the space between the members G as is shown in Fig. 5, they may be bent inward, as at D to retain a firm grip on the pin M and then again spread apart to form the arms G It is obvious that my improved stop may be embodied in a considerable variety of forms other than those shown. For example, by a slight modification it may be adapted for attachment to either the fixed or the movable member of the hinge and arranged so as to bear against the other member to prevent the closing of the blind, or the details may be varied in ways obvious to those skilled in the art without departing from the spirit of my invention.

Vhat I claim is 1. The combination with a stop for window-blinds of means for attaching the same to one member of the hinge, a swinging and reciprocating arm B carrying said stop and adapted to swing said stop into and out of the path of the other member of the hinge, said arm being provided with a slot B, and a pin F in position to be engaged by said slot to lock said stop in such path.

2. The combination with a stop for window-blinds, of a pair of plates G2 carried by the fixed member of the hinge, a pin E between said plates, and a swinging arm carried by said pin and carrying said stop.

3. The combination with a stop for window-blinds, of a pair of plates G carried by the fixed member of the hinge, pins E and F between said plates, and a swinging and reciprocating arm B carried by said pin E and provided with a slot B in position to engage said pin F to lock. said arm.

4. The combination with a stop for window-blinds, ot' a sleeve for attaching the same to the hub of the fixed portion of the hinge, said sleeve comprising a pair of members adapted to surround said hub and being extended to form plates G and said stop being carried between said plates.

5. The combination with a stop for window-blinds, of a sleeve carrying said stop and adapted to surround the hub of the fixed member of the hinge, a fillet K adapted to bear at its edge K against such fixed member, and a screw passing through the sleeve and having a flat end adapted to bear against the flat face K of said fillet, whereby the sleeve may be prevented from turning on the hub.

6. The combination with a stop for window-blinds of means for attaching the same to a window-frame, means for swinging said stop into and out of the path of the blind, and means for adjusting said stop laterally.

7. The combination with a stop for window-blinds of means for attaching the same to one member of the hinge, means for swinging said stop into and out of the path of the other member of the hinge, means for locking said swinging means in position, and means for adjusting said stop laterally.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
